WALTER G. SIMMONS, OF GASSAWAY, WEST VIRGINIA.

GAS-CONTROLLING nnvrcn.

This invention pertains to a new and useful gas controlling device, adapted mainly for use in connection with branches of gas mains, and the object of the invention is to provide a device of this design, which is simple in construction, practical and durable in practice.

A further object of the invention is the provision of a' weighted diaphragm, which may be actuated by the pressure of gas for drawings in connection therewith, w

holding the valve unseated, in order to allow the flow of gas to enter a building; that is to say, the diaphragm holds the valve unseated after the same has been manually raised.

Another object of the invention is to provide means for inclosing the diaphra thereby providing a pressure chamber be ow said diaphragm, and into which the as from the main flows, that is to say, a or passingthe valve.

Another object of the invention is the production of a compound or double valve, which may contact with a valve seat if raised or lowered sufiicient for such purpose.

Another object of the invention is to produce an angular member having adjustable connections for supporting the said valve.

This invention comprises further objects and combinations of elements which will be hereinafter more fully described, shown in the accompanying drawings, and the novel features thereof will be pointed out by the ap ended claim. i

o obtain a full and correct understanding of the details of construction, combinations of features, elements and advantages,

reference is to'be had to the hereinafter set forth description and the accom anying erein--- Figure l is a sectional view through the gas controlling device, and showing. the same a lied -to' alateral branch of" a gas main. ig. 2, is a 'view similar to-Fig. 1,

and the valve raised. Fig. 3 is a sectional view upon line 33 of Fig. 1.

Referring to the annexed illustrations 1 designates a gas main, from which a lateral branch 2'extends.,- This lateral branch comprises two sections 3 and 4; the section 3 is connected to a gas main by a suitable T- union 5, and also connected to the section 3 by means of threads is a valve casing 6, as shown. The section 4 is connected to the valve casing by threads, asshown clearly in Fig. 1. This valve casing is provided with a central wall 7, which is provided with valve seats 8, with which the valve 9 cooperates, as will be clearly apparent. This valve 9 is of. the compound or double type design, and projecting from the u per and lower face thereof are lugs 10, the ower one of which engages an aperture 11 of a horizontal portion 12 of the angular member 13, which supports said valve. To hold the lug in engagement with the horizontal portion 12 a nut or other threaded member 14 is threaded to .the lug as clearly shown. This valve comprises two parts 15 and 16 (which are connected together by means of a threaded In and recess 17 and 18); the upper part 0 the valve contacts with the upper valve seat, while the lower part 16 of the valve 006 erates with the lower valve seat. The wal 7 divides thevalve easing into two chambers 19 and 20, and in the chamber 19 the greater part of the angular member 13 is disposed, with the upper portion of the angular member, (which is proclearly disclosed in Figs. '1 and-2.

The diaphragm chamber is formed by an upper annular extending wall 25 and the cap plate, cover or closure 26, (which are con-.

nected together by cap screws or bolts or other means 27, as clearly shown), and tween which the diaphragm 28 is disposed, the said ca screws or bolts or other means penetrate t rough the diaphragm, as shown in order to holdthe same properl in place. This diaphragm (which is provi ed with a weight 29) dlvides the diaphragm chamber ,into an upper chamber and a lower chamber which is the pressure chamber 30). The

iaphra adjacent to its annular periphery, an the anpular wall 25 areprovided ioo . or raised, sufiicient to contact with the knob,

with bulged portions 31 adapted to fit or register with one another. The annular bulged portion of the diaphra is designed for the purpose of lending fiibility and pliability, while the weight 29 afi'ords rigidity and assists in returning the diaphragm to its normal position, after pressure thereupon is relieved.v

V The aperture 22 of the wall 23 is not only of a sufiicient diameter to admit of the vertical portion 32 of the angular member 13, but is large enough to allow gases after passing the valve to enter the pressure chamber 30. When the gases are admitted in to the pressure chamber, the diaphragm is held in a vibrated position. When the gases are under low pressure, the diaphragm is returned to its normal position, or as shown in Fig. 1.

Ordinarily or when the pressure of gas is out off, the moving parts of the device are approximately in the positions as shown in Fig. 1; to allow the gases to enter or pass through the section 4 of the lateral branch and into the pressure chamber 30 after passing the valve, the plug 34 (which is threaded into an opening 35 of the cap'plate 26), is removed. After this the valve is raised manually, by taking hold of the knob or handle 36 of the upper vertical portion 37 of the angular member 13, as will be clearly evident. After the valve is raised the gas is admitted into the chamber 19, from which it passes through the section 4 of the lateral branch, and also through the aperture 22 into pressure chamber 30. As before set forth, the action of the gases after entering the chamber 30 hold the diaphragm vibrated or handle 36, thereby holding the valve raised, until the high pressure of gas is shut 05, as will be obvious.

Ihe upper vertical portion 37 is adjustably connected to the horizontally disposed portion 21 of the angular member 13, by means of suitable threaded connections 39, there being a lock nut 40 to hold the connections in their adjusted positions. The wall 23 is rovided with an opening 41 (which is closed by a cap or plug 42), said plug or cap is provided with a recess 43 to receive the projecting end of the vertical portion 21 of the angular member 13 and the lock nut, that is, when the valve and said member 13 are in their lowermost positions. The lower portion of the valve casing is provided with an opening 44 (which is closed by a threaded cap, plug or other means 45).

From the foregoing, the essential features,

elements and the operation of the device, together with the simplicity thereof, will be clearly apparent.

Having thus fully described the invention, what is claimed as new and useful, is:

In combination, a diaphragm casing made in two parts, a diaphragm secured between the two parts, a plate positioned on the upper side of the diaphragm, a pin extending through the late and diaphragm, a valve casing formed on one of the parts of the diaphragm casing, said casing being provided with a wall having a slot therein, an angular wall in a valve casing formed with a valve seat, a double valve movable against the seat, and means movable in the slot of the wall first named connecting the pin with the valve.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
